You would enter your rent in the "Other, Specify" box in the "Expenses which you incurred for the entire home" section. Since you lived in 2 different places, you would add the rent of the first place you lived and the 2nd place you lived and enter that. TurboTax will then calculate your allowable expense. Same thing goes for your other expenses in the "Expenses which you incurred for the entire home" section.
